Best ResponseYou've already chosen the best response.1we can simplify your function. For example, we can factor out 9 at numerator and 3 at denominator, so we can write this: \[\Large \frac{{9{x^2} + 9x  18}}{{3x + 6}} = \frac{{9\left( {{x^2} + x  2} \right)}}{{3\left( {x + 2} \right)}}\]

Best ResponseYou've already chosen the best response.1in order to do that, we have to find two numbers such that their sum is 1 and their product is 2

Best ResponseYou've already chosen the best response.1ok! sorry,then the simplified expression of our function is: \[\Large \begin{gathered} \frac{{9{x^2} + 9x  18}}{{3x + 6}} = \frac{{9\left( {{x^2} + x  2} \right)}}{{3\left( {x + 2} \right)}} = \hfill \\ \hfill \\ = \frac{{9\left( {x + 2} \right)\left( {x  1} \right)}}{{3\left( {x + 2} \right)}} = 3\left( {x  1} \right) \hfill \\ \end{gathered} \]

Best ResponseYou've already chosen the best response.1if I set y=0, then I get x=1, so our line has to pass at point (1,0)

Best ResponseYou've already chosen the best response.1furthermore if I set x=2 then I get y=3, so correct!! :)
